Baxi EcoBlue + Combi

The Baxi EcoBlue + Combi boasts only high-quality parts and delivers excellent heating and hot water performance.

Need a powerful condensing gas combination boiler that comes with an impressive warranty? The Baxi EcoBlue + Combi could be just what you require. It is a compact solution that can fit into a kitchen cupboard and is available in three heat outputs to appeal to most styles and sizes of homes. Better still, this attractively priced boiler is A-rated for efficiency, so it should save you a nice chunk of money on your fuel bills.

How Much Does this Boiler Cost?

Because the Baxi EcoBlue + Combi can be supplied with an output of 24kW, 28kW or 33kW, prices start at around £830 and go up to £1000 including VAT. As you’ve probably guessed, the highest output option will be the most expensive of the three. Prices also vary from one supplier to the next, so it’s always worth shopping around to see if you can save a bit of money. When speaking to boiler providers and installers, don’t forget to get quotes on the installation because the fitting costs aren’t usually included in the price of the boiler.

How will I know if this Boiler is Suitable for My Home?

To be honest, you won’t know for sure without getting in contact with a Gas Safe registered engineer. We can tell you that most combi boilers are ideal for homes that are tight on space, which is mainly down to the fact that they don’t need a separate cold water tank or hot water storage cylinder. They do, however, find it hard to cope when two showers are running at the same time, meaning combi boilers aren’t generally suited to properties with multiple bathrooms.

Like all combi boilers, the Baxi EcoBlue + Combi will ensure instant hot water is always available and make sure you only ever pay for the hot water you actually use. The trouble is, this boiler won’t be the correct type for every home and is why we suggest you consult a Gas safe registered engineer. You also need to know the right heat output for your flat or house before purchasing a new boiler, which is something a qualified professional will be able to tell you.

Is it a High Efficiency Boiler?

It’s an A-rated boiler, meaning it will provide high levels of efficiency. On top of that, the Baxi EcoBlue + Combi is Energy Saving Trust endorsed, so you can rest assured that it meets industry agreed standards for energy performance and will cut the cost of your fuel bills. There is also a wide range of optional controls available that can be combined with the boiler to help not only improve user comfort buy also energy efficiency levels. Furthermore, the EcoBlue + is compatible with the uSense smart control that lets you monitor your energy use and control the boiler from your smartphone when using the 230v switch live.

Does this Boiler have a Good Range of Controls and Features?

Yes, it does. The Baxi EcoBlue + Combi has concealed user controls, making this boiler ideal for families with young children. Key controls include an operating mode selector, adjustable central heating and hot water temperature switches and a clear LCD display with fault diagnosis. The boiler comes with a full wall-mounting jig and a choice of flue lengths, giving you the ability to choose where the boiler is installed. It also has front access to all of the components to make life easy during installation and annual servicing.

How long is the Warranty on this Boiler?

If you go on to purchase the Baxi EcoBlue + Combi, you’ll get a lengthy 7-year parts and labour warranty as standard.
